Název v původním jazyce

Analysis of Stochastic Character of Yarn Waviness in Woven Composites (Proc. of Eleventh International Conference on Composites/Nano Engineering)

Popis výsledku v původním jazyce

Yarn longitudinal axis in textile composites exhibit random component. Statistical methods for the description of this feature are used in two ways, minimally. The first way approximates the yarn axis by the Fourier series using DFT. After applying the Dsamples, the statistical distribution of spectral lines is searched. The second approach considers the yarn axis as a realisation of random process and applies relevant statistical methods. The most important method is correlation that allows finding difyarns. Also the verification of stationarity and ergodicity of random process can be used. Results have shown that amplitudes and phases of spectral lines do not have normal and uniform distribution, respectively, as it had been expected. The correlatioto yarn shape difference, but it is sensitive to frequency change. Both the stationarity and ergoditicity were confirmed.
